you have to use evox M7, but you do need a 29 wire mod to reflash your TSOP, however you can flash your x2 lite (assuming its a 2.2) will be able to boot with M7, you just wont be able to disable it
however, a trick to get you on Live (if you so desire) would be to flash you chip with half original and half M7, so you can just change your bios bank to boot retail and go on Live (that should work, assuming the chip does not allow the top half of the bioschip to see the bottom half)
